Information
Radiator water / coolant, additional, middle.
High-quality OE Match replacement Additional Middle Water Radiator is a cooling core designed for the centre position in the front cooling system of the Porsche 992 (911). It supplements the main side radiators to increase overall cooling capacity, helping maintain optimal engine operating temperatures under demanding driving conditions.
Fits:
for vehicles with additional coolant radiator
Porsche 992.1 Carrera 2019 - 2024
Porsche 992.2 Carrera 2024 >>
Porsche 992 Turbo 2020 >> (PR:8Z6, 8Z8)
Diagram ref no 1
Modern Porsche 992 models use a multi-radiator cooling layout, with left, right, and additional centre radiators working together to manage thermal loads from turbocharged engines. The additional middle radiator increases total heat rejection capacity, particularly during high-speed driving, spirited use, or hot ambient conditions.
Designed as a direct-fit replacement, it installs into the factory centre radiator position using existing mounts and coolant lines without modification.

Modern Porsche 992 models use a multi-radiator cooling layout, with left, right, and additional centre radiators working together to manage thermal loads from turbocharged engines. The additional middle radiator increases total heat rejection capacity, particularly during high-speed driving, spirited use, or hot ambient conditions.
Designed as a direct-fit replacement, it installs into the factory centre radiator position using existing mounts and coolant lines without modification.
The additional middle radiator enhances the vehicle’s cooling system by:
• Increasing total coolant heat dissipation
• Supporting turbocharged engine thermal management
• Reducing heat-soak during aggressive driving
• Maintaining stable operating temperatures
• Helping preserve engine efficiency and longevity
Function
• Acts as supplementary heat exchanger in the centre cooling circuit
• Transfers engine heat from coolant to ambient airflow
• Supports consistent turbo and engine performance
• Works in conjunction with side radiators and cooling fans
A failing centre radiator can reduce overall cooling efficiency, causing higher engine temperatures, reduced performance under load, and increased fan operation. Left unchecked, poor heat management can place unnecessary thermal stress on critical engine components. Replacing a damaged or weakened radiator with a quality OE Match unit restores proper cooling performance and helps protect your Porsche engine from overheating and premature wear.
Replace the radiator if you notice coolant leaks, visible core damage or bent fins, overheating during heavy driving, or after front-end impact. It is also recommended during a cooling system overhaul or performance upgrade.
